at least one or more transmission dummy patterns respectively formed between the respective transmission patterns; and
and one or more reception dummy patterns respectively formed between the respective reception patterns. 8 . The electronic device of claim 7 , wherein the transmission dummy patterns and the reception dummy patterns overlap each other and are disposed in directions that cross each other. delete delete The electronic device of claim 1 , wherein the touch screen display panel includes one of an LCD display panel and an OLED display panel. The electronic device of claim 1 , wherein the input sensing panel includes a digitizer. The electronic device of claim 1 , wherein a cushion layer made of an elastic material is further disposed between the display panel and the input sensing panel. In electronic devices,
A transparent substrate made of synthetic resin;
a display panel disposed on a lower surface of the transparent substrate and having first and second surfaces facing each other;
A touch screen panel disposed on the first surface of the display panel;
A digitizer panel disposed on the second surface of the display panel through a compression process, wherein the digitizer panel
digitizer circuit board;
at least one signal pattern formed on a first surface of the digitizer circuit board; and
It is formed on the first surface of the digitizer circuit board and includes at least one non-signal pattern disposed between each of the signal patterns,
The touch screen panel
a flat touchscreen display; and
A curved touch screen display disposed at an edge of the flat touch screen display,
When the touch screen panel is viewed from above, non-signal patterns are formed between the signal patterns in the first area where the flat touch screen display is disposed, and in the second area where the curved touch screen display is disposed. An electronic device in which the non-signal patterns are not respectively formed between the respective signal patterns. 15. The electronic device of claim 14, wherein each of the signal patterns has a linear shape extending in a first direction at regular intervals, and each of the non-signal patterns has a linear shape extending in the first direction. 16. The method of claim 15, wherein each non-signal pattern has the same thickness as each signal pattern, and each non-signal pattern is formed in the same plane as each signal pattern,
The electronic device of claim 1 , wherein a concave-convex pattern is not visible on the digitizer panel when viewed through the touch screen panel from above. delete delete delete delete delete delete delete delete delete delete delete
